I bought Samsung LED during the launch of 1st model of the Samsung LED which the price of 40" 7 Series was at peak high at RM7990.00 with no 3D features. At same price now you can buy 46" 3D series 7 models.
But now looks like quality of the Samsung LED also degraded. Two of my friends LED 3D series LED panels were replaced as no image just after 2-3 weeks.
